Placing the legend at the right side gives a correct result

Hi Yeray,

the public tracker says RESOLVED FIXED.
And you are telling there that the file Chart.pas is updated. So where to get it?

Hello Yeray,

I'm very sorry but the bottom legend is still wrong.
I need to use a legend with checkboxes.

In my own program I get now the legend displayed correctly but get a wrong behaviour. So a click on some checkboxes switches on/off the wrong series. To switch on/off a desired series I need to click beside a checkbox in the legend text. This means that the mouse position is not calculated correctly.

As it is difficult to send the full source code I have tried to make an example. The example also behaves wrongly but a bit different (some checkboxes are missed but you can click also on the text). Anyway you can see a malfunction and check what's wrong.

So simply drop a TChart component on a project form and run

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
var i: integer;
    SeriesArray: array[0..5] of TChartSeries;
begin
  Form1.Width := 800;
  Form1.Height := 400;
  Chart1.Legend.CheckBoxes := true;
  for i := 0 to High(SeriesArray) do
  begin
    SeriesArray[i] := TLineSeries.Create(Chart1);
    SeriesArray[i].FillSampleValues(100);
  end;
  Chart1.AddSeries(SeriesArray);
  for i := 0 to 5 do
    Chart1.Series[i].Title := 'this is long series title '+IntToStr(i);
end;
As I like to deploy a correct version of my program a quick fixup would be very appreciated.

Hi Uli,

I've tried this with both v2015.14 and with the current internal sources we have here and it seems to work fine in both:

Here it is the project I used:

Am I missing anything?

i just downloaded the TeeChart Pro v2012/14 VCL version today and also have this misaligned legend checkbox error.

can you please send me the modified unit as well?

also, is there a way to automatically update teechart without individually requesting each patch?

thank you,

Tracey

I see you don't have the sources so I'm preparing a TeeChart Pro BETA installer for XE7.
I'll send the link to it as soon as possible.

Yes, with the regular maintenance releases. However, if we consider a fix is important enough, we are glad to prepare beta installers.

Hello Yeray,

I have downloaded your test project testBottomLegendCheckboxes.zip

hi yeray:

thanks for the TeeChart Pro BETA installer for XE7. it fixed the misalignment problem.

however now on plots where the legend is more than one row, the checkboxes in all but the first column are not visible, similar to what was reported by uli above. i am also using 2D plots.

thanks!

Tracey

Hello Uli and Tracey,

You are right the change I proposed doesn't seem to fix this in some circumstances.
I've reopened the ticket so it can be reviewed:

Hello Yeray,

now a month has passed but no solution up to now.
Ticketing a bug in the database, even with importance 'high major' does not solve anything. Someone must try to fix the bug.
So may I kindly ask you what's happening ? It's "just" 16 bugs reported for VCL TeeChart since then still open, only 2 bugs solved. So is no one dealing with them ?
I would be quite bad if I need to wait for the release of a next version.

Uli
